to much oil!!!!!!! ARG
k so just to start off, i decided to turbo my suzuki katana 600. Basicly everythings done, went with a KKK KP31 turbo from a smart car, so go out the next day, oil just everywhere, start it up. Oil spraying everywhere, in the end just picked up another one my buddy had for 100$. redid all the fab, start it. works great. decided to rev it. hit about 5k. oil starts coming out... basicly in the end i need to cut the oil press./flow down.... what size restrictor should i use?
|
journal bearing turbo use a 0.060" orifice.
roller bearing turbo use a 0.035" orifice. |
make sure your turbo drain is gravity feeding otherwise you will need a scavenge pump. this will also cause excess oil leaking/burning from the turbo.
|
i have a scavenger pump on it. it runs great at idle, but as soon as im hittin 5/6K oil started coming out.....im sorry but i dont know if its a journal or a roller. could you tell me? and could you give me a link to where i can purchase these, i need a 1/8"
|
looks like its a journal.
|
also what does the restrictor drop it to.
|
there all over ebay. a .060" orifice should drop the oil pressure to ~15-25 psi.
|
ok, some guy on the smart car forum said .040"..... man this sucks lol
|
if its a journal bearing turbo use a flange with an orifice of 0.060". ive built many turbo cars and bikes and i always use a 0.060" orifice and have never had an issue.
|
ok thank you!, ill go though and upload my build for the bike so you can all see it. ill order that restrictor tonight, thanks!
|
.065" restrictor ordered... lets see what happends..........
|
i got the oil restrictor in the mail today, i emailed the seller a few times to no responce so i thought id ask here... i remember seeing one listing that said the restrictor is directional. as in the female end needs to be toward the turbo..... anyone know if i need to? it doesnt matter i can install it either way, but want to know if it forsure needs to be..... heres what i bought. eBay (item 390289291588
heres the one i was saying is directional eBay (item 310294102836 |
anyone know? im waitin to toss this on.
|
the threaded end goes into the turbo and your oil line goes into the other end.
|
thats what i thought, just had to double check... you know how stuff is now days....
